Definitions
- the invention relates to a pipeline connection between a metal-encapsulated, pressure-gas-insulated high-voltage switchgear and a transformer, which in particular contains a compensator and in which the pipe-conductor is connected on one side to a connection of the metal-encapsulated, gas-insulated high-voltage switchgear and on the other side to a transformer outlet.
- Such pipe connections are common and z. B. from E-Bl-0 055 094 known.
- the compensator in the pipeline connection allows a certain tolerance range for the fastening of the pipeline to the adjacent connection piece. This possible tolerance range depends on the permissible movements given by the dimension of the compensator in the direction of its longitudinal axis ⁇ L and the permissible angular movements ⁇ . The tolerance range that can be determined by the angular movements is also dependent on the distance L between the compensator and the flange connection piece used for connection.
- the possible tolerance compensation is primarily dependent on the dimensioning of the compensator, which is a complex component and which tends to be able to buckle easily in the event of large axially permissible movements because of the large number of fold turns required, so that only the permissible axial deflection of the compensator can be used for tolerance compensation.
- the invention is therefore based on the object of a pipe connection with or without a compensator between one
- the distance between the flange connector of the transformer outlet and the pipe connector provided with a lateral flange connection can be rotated in the axial direction, i.e. in the direction of the longitudinal axis of the pipe the center axis of the second rotary flange are balanced.
- the middle part of the encapsulated Z-shaped or U-shaped pipe connector part is then inclined accordingly.
- the possible compensatable tolerance range is not limited by the permissible movement of the compensator in the axial direction, but rather the possible tolerance range is given by the distance between the center points of the two rotary flanges and by the permissible angular deflection of the compensator and has an ellipsoidal shape.
- the permissible axial movement of the compensator can therefore be neglected.
- a corresponding compensatable ellipsoidal tolerance range is obtained when the second rotary flange is connected to the end surface of the pipe. This tolerance range lies in a plane running parallel to the end face of the pipe.
- Another level of the compensable tolerance range which is at right angles to this, is obtained when connecting a Z- or U-shaped encapsulated pipe connector part via the first rotary flange on the end face of the transformer outlet, if the end face of the transformer outlet is below the pipe connector and the pipe conductor has a lateral flange connection.
- the compensator is expediently arranged in this pipeline connection adjacent to the connection of the metal-encapsulated, compressed gas-insulated high-voltage switchgear so that the permissible angular deflection can be exploited to the greatest possible compensatable tolerance range.
- the transformer outlet and the pipeline are each connected via a rotary flange to one end of a Z-shaped, encapsulated tubular connector part and the other two ends of the Z-shaped tubular connector parts are connected to one another by a further rotary flange.
- the compensatable tolerance range is increased to a circular ring area and the effort given by a compensator is eliminated.
- the compensable tolerance ranges are also in three planes at right angles to each other.
- FIGS. 1 and 6 show the basic structure of a pipeline connection designed according to the invention between a metal-encapsulated, compressed gas-insulated high-voltage switchgear and a transformer.
- Figures 2, 3 and 7 each show a view A of the transformer with connected pipe connection in modified embodiments.
- Figures 4, 5 and 8, 9 schematically show the possible compensable tolerance ranges of an arrangement according to Figure 1 or 6 depending on the dimensions of the pipe connections.
- Figure 1 shows a metal-encapsulated, compressed gas-insulated high-voltage switchgear 1 consisting of a pressure vessel 2 with a circuit breaker and a double busbar system 3. This is connected to the transformer 5 via a pipe connection 4.
- the pipe connection 4 contains a compensator 6, which is arranged adjacent to the connection 7 of the metal-encapsulated, compressed gas-insulated high-voltage switchgear 1 and is fastened to it.
- the pipeline 8 of the pipeline connection 4 extends between the compensator 6 and the transformer outlet 9 and ends in a flange stub 10 oriented at right angles to its longitudinal axis, the connection surface 11 of which lies in a plane running parallel to the plane of the longitudinal axis of the pipeline 8.
- the transformer outlet 9 has a lateral flange connection 12, which extends at right angles to its longitudinal axis, the connection surface 13 of which is also in a
- R there is a height difference R between the central axes of the flange connections 10 on the pipeline 8 and 12 at the transformer outlet 9, which is indicated in FIGS. 2 and 3 by arrows.
- a U-shaped, encapsulated pipe connector 14 (FIG. 3) or a Z-shaped encapsulated pipe connector 15 (FIG. 2) is used
- Distance R between the center axes of the flange connector 10 on the pipe 8 and the flange connector 12 on the transformer outlet 9 is bridged.
- These Z- (15) or U- (14) -shaped, encapsulated pipe connector parts are connected at one end to the flange connector 12 of the transformer outlet 9 via a first rotary flange 16.
- the other end of the encapsulated pipe connector part 14, 15 is each connected to the flange stub 10 of the pipe 8 via a second rotary flange 17.
- the distance between the central axes of the two rotary flanges 16, 17 thus corresponds to R.
- These rotary flanges 16, 17 are common components in pressurized gas-insulated, metal-enclosed high-voltage switchgear and allow the parts connected via them to be rotated relative to one another.
- H the longitudinal axis of the pipe 8 above the foundation 18, which is indicated in FIG. 1 by arrows
- the Z- or U-shaped encapsulated pipe connection part 14, 15 can be rotated around the flange connection 10, so that the flange connection 12 of the transformer outlet 9 could lie on the circle with the radius R, which thus represents an essential determining variable for the compensatable tolerance field T 1 or T 2 (see FIGS. 4 and 5).
- the compensatable tolerance field T 1 or T 2 is not only dependent on the radius R, but also on the possible one
- Angular movement ⁇ of the compensator 6 limited.
- This compensator 6 allows an allowable angle determined by its dimensions (represented by arrows in FIG. 1), around which the compensator 6 can perform angular movements above or below the longitudinal axis of the pipe 8.
- H L tan
- the partial area F h is not part of the compensable
- connection surface 13 on the flange 12 of the transformer outlet 9 is not within the
- Area F h may be.
- FIGS. 6 and 7 show a further modified embodiment of the invention. The same reference numerals are retained for the same parts.
- the pipeline connection 4 between the metal-encapsulated, compressed gas-insulated high-voltage switchgear 1 and the transformer 5 has no compensator, so that the pipeline 8 is connected directly to the connection 7 of the metal-encapsulated, pressurized gas-insulated high-voltage switchgear.
- For the connection between the pipe 8 and the transformer outlet 9 serve two Z-shaped, encapsulated pipe connector parts 19, 20, which with the flange 12 of the transformer outlet or with the flange 10 of the pipe 8 each via a rotary flange 16, 17 and with each other over the other Rotary flange 21 are connected.
- the leg length R of the Z-shaped, encapsulated pipe connector part 19 corresponds to the distance between the central axes of the rotary flanges 17 and 21 and the leg length S of the Z-shaped tube conductor connects part 20 corresponding to the distance between the center lines of the rotary flanges 16 and 21.
- the distances R and S are indicated in FIG. 6 by arrows.
- the permissible compensatable tolerance field T 3 , T 4 is therefore solely dependent on the sizes R and S.
- the compensatable tolerance field T 4 shown in FIG. 8 results in the form of a circular ring.
- the outer radius R a of this tolerance field T 4 has the size R + S.
- the inner radius R i corresponds to the absolute value of the difference between the values of the two radii R and S.
- the rotary flange 16 at the transformer outlet 9 may only lie within the circular area of the tolerance field T 5 .
